Why are @Context fields not populated in cxf?

Question

Apache HTTP Server

@Service
@Transactional
@Path("test")
public class ServiceImpl implements Service {
    @Get
    public void test(@Context MessageContext ctx) {
    }
}

issues 404

@Service
@Transactional
@Path("test")
public class ServiceImpl implements Service {
    @Context MessageContext ctx;
    @Get
    public void test() {
    }
}
